I've integrated an Apple sign in for Flutter.
Everything is working fine until the point when I have to logout from the Stores() page.
The app landing page (Home) shows a series of buttons to login with different apps:
Google
Anonymous
Apple
Email & Password
All of them are able to logout by using a logout button, but not Apple.
Here is my code
main.dart
class Main extends StatelessWidget {
#override
Widget build(BuildContext context) {
return StreamProvider<User>.value(
value: AuthService().user,
child: MaterialApp(
home: Wrapper(),
routes: {
"/stores": (_) => Stores()
},
));
}
}
Wrapper.dart
class Wrapper extends StatelessWidget {
#override
Widget build(BuildContext context) {
final user = Provider.of<User>(context);
if (user == null) {
return Home(); <-- Landing page before login
} else {
return Stores(); <-- Landing page after login, where the logout button is
}
}
}
Home.dart
class _HomeState extends State<Home> {
final AuthService _auth = AuthService();
bool loading = false;
final welcomeText = 'Welcome';
final subtitle = 'Make grocery chores easier';
final anonymousButtonText = 'Skip';
#override
Widget build(BuildContext context) {
return Stack(children: [
AuthLayout(),
Scaffold(
backgroundColor: Colors.transparent,
appBar: AppBar(
title: Center(child: Text(welcomeText)),
backgroundColor: Colors.transparent,
),
body: SingleChildScrollView(
child: ConstrainedBox(
constraints: BoxConstraints(),
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget> [
// Sign In with Apple
Padding(
padding: EdgeInsets.all(8.0),
child: FutureBuilder<Object>(
future: _auth.appleSignInAvailable,

if (snapshot.data == true) {
return AppleSignInButton(
onPressed: () async {
FirebaseUser user =
await _auth.appleSignIn();
if (user != null) {
Navigator.pushReplacementNamed(context, "/stores");
}
},
);
} else {
return Container();
}
})) ....
AuthService.dart
class AuthService {
final FirebaseAuth _auth = FirebaseAuth.instance;
final GoogleSignIn _googleSignIn = new GoogleSignIn();
// Create user object based on FirebaseUser
User _userFromFirebaseUser(FirebaseUser user) {
return user != null ? User(uid: user.uid) : null;
}
// Auth change user stream
Stream<User> get user {
return _auth.onAuthStateChanged.map(
_userFromFirebaseUser);
}
// SignIn with Google
Future signInGoogle() async {
GoogleSignInAccount googleSignInAccount = await _googleSignIn.signIn();
GoogleSignInAuthentication googleSignInAuthentication =
await googleSignInAccount.authentication;
AuthCredential credential = GoogleAuthProvider.getCredential(
idToken: googleSignInAuthentication.idToken,
accessToken: googleSignInAuthentication.accessToken);
try {
AuthResult result = (await _auth.signInWithCredential(credential));
FirebaseUser user = result.user;
return _userFromFirebaseUser(user);
} catch (e) {
print(e.toString());
return null;
}
}
// SignIn with Apple
// Determine if Apple Signin is available on device
Future<bool> get appleSignInAvailable => AppleSignIn.isAvailable();
Future appleSignIn() async {
try {
final AuthorizationResult appleResult =
await AppleSignIn.performRequests([
AppleIdRequest(requestedScopes: [Scope.email, Scope.fullName])
]);
if (appleResult.error != null) {
// handle error from Apple
}
final AuthCredential credential = OAuthProvider(providerId: 'apple.com')
.getCredential(
accessToken: String.fromCharCodes(
appleResult.credential.authorizationCode),
idToken:
String.fromCharCodes(appleResult.credential.identityToken));
AuthResult result = (await _auth.signInWithCredential(credential));
FirebaseUser user = result.user;
return user;
} catch (error) {
print(error);
return null;
}
}
// SignOut
Future signOut() async {
try {
return await _auth.signOut(); <-- Should I do something different here for Apple?
} catch (e) {
print(e.toString());
return null;
}
}
}
All the other apps logout correctly, but Apple doesnt. Should I do something different in the signout since it's using /routes?
Any help is much appreciated!!
Many thanks
Joe
await _firebaseAuth.signOut();
Use the above code for signout
and check firebase IOS configuration
Should be fine, make sure that you have followed the steps described here:
https://firebase.google.com/docs/auth/ios/apple
Which means your application needs to fulfill the following requirements to make apple sign in work properly:
Be a member of the Apple Developer Program
Enable Sign In with Apple for your app on the Certificates, Identifiers & Profiles page of Apple's developer site.
Enable Apple as a sign-in provider on firebase
Want to enable/disable a button based on user input. If all text input matches a certain condition, only then enable the "insert" button.
Normally button gets only enabled, if all the input field is correct. But if one or more incorrect, and user moves to another input field, and change it to correct/incorrect, button gets enabled, even if some field has wrong input. Check image:
Code for login bloc:
import 'package:rxdart/rxdart.dart';
class LoginScreenBloc {
final _firstCtrl = BehaviorSubject<String>();
final _lastCtrl = BehaviorSubject<String>();
final _userNameCtrl = BehaviorSubject<String>();
final _passwordCtrl = BehaviorSubject<String>();
Function(String) get changeFirst => _firstCtrl.sink.add;
Function(String) get changeLast => _lastCtrl.sink.add;
Function(String) get changeUser => _userNameCtrl.sink.add;
Function(String) get changePass => _passwordCtrl.sink.add;
final fieldSize = StreamTransformer<String, String>.fromHandlers(
handleData: (value, sink) {
if (value.length > 3) {
sink.add(value);
} else {
sink.addError("Can't be Empty!");
}
},
);
Stream<String> get firstname => _firstCtrl.stream.transform(fieldSize);
Stream<String> get lastname => _lastCtrl.stream.transform(fieldSize);
Stream<String> get username => _userNameCtrl.stream.transform(fieldSize);
Stream<String> get password => _passwordCtrl.stream.transform(fieldSize);
void insertValue() {
print("${_firstCtrl.value}");
print("${_lastCtrl.value}");
print("${_userNameCtrl.value}");
print("${_passwordCtrl.value}");
}
Stream<bool> get insertButton {
return CombineLatestStream(
[firstname, lastname, username, password],
(values) {
return true;
},
);
}
dispose() {
_firstCtrl.close();
_lastCtrl.close();
_userNameCtrl.close();
_passwordCtrl.close();
}
}
Code for the button:
Widget insertValue(BuildContext context, LoginScreenBloc bloc) {
return StreamBuilder<Object>(
stream: bloc.insertButton,
builder: (context, snapshot) {
return RaisedButton(
child: Text("Insert"),
onPressed: snapshot.hasData ? bloc.insertValue : null,
);
},
);
}
try to used opacity connect for button enable and put the condition for click and visiblity.. like this way..
Container(
child: Opacity(opacity: isValid ? 1.0 : 0.7,
child: RaisedButton(
color: Colors.red,
onPressed: _loginPressed,
child: Text('Sign In',
style: TextStyle(fontSize: 15.0, color: Colors.white)),
),
),
),
Something Similar you can find here
Stream<bool> get insertButton {
return CombineLatestStream(
[firstname, lastname, username, password],
(values) {
for(String i in values) {
if(i.length < 3) return false;
}
return true;
},
);
}
combineLatest only checks for event. It doesn't takes care of the error which gets out from the stream.
I found a solution that worked for me.
I had the same issue while building a login form.
This is my code:
class LoginFormManager with FormValidatorMixin {
final _email = BehaviorSubject<String>();
Stream<String> get email$ => _email.stream.transform(emailValidator);
Function(String) get setEmail => _email.sink.add;
final _password = BehaviorSubject<String>();
Stream<String> get password$ => _password.stream.transform(passwordValidator);
Function(String) get setPassword => _password.sink.add;
Stream<bool> get isFormValid$ =>
CombineLatestStream.combine2<String, String, bool>(email$, password$,
(email, password) {
if (email == _email.value && password == _password.value) {
return true;
} else
return false;
});
void submit() {
print(_email.value);
print(_password.value);
}
void dispose() {
_email.close();
_password.close();
}
}
The subjects _email and the _password store the last value received including errors.
The email$ and password$ streams only send data when the input received from the user passes the validators.
So in my case I just had to check if the email and password$ sent by email$ and password$ match the last value stored in the subjects of the _email and the _password.
I want to render a local HTML file stored in my phone memory in webview using flutter and dart.
I am using the webview_flutter plugin from the Flutter Team.
Steps
Add the dependency to pubspec.yaml:
dependencies:
webview_flutter: ^0.3.20+2
Put an html file in the assets folder (see this). I'll call it help.html.
Get the html string in code and add it to the webview.
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:webview_flutter/webview_flutter.dart';
class HelpScreen extends StatefulWidget {
#override
HelpScreenState createState() {
return HelpScreenState();
}
}
class HelpScreenState extends State<HelpScreen> {
WebViewController _controller;
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Help')),
body: WebView(
initialUrl: 'about:blank',
onWebViewCreated: (WebViewController webViewController) {
_controller = webViewController;
_loadHtmlFromAssets();
},
),
);
}
_loadHtmlFromAssets() async {
String fileText = await rootBundle.loadString('assets/help.html');
_controller.loadUrl( Uri.dataFromString(
fileText,
mimeType: 'text/html',
encoding: Encoding.getByName('utf-8')
).toString());
}
}
Notes:
I needed to set the encoding to UTF-8 because I was getting a crash for non-ASCII characters.
In iOS you need to add the key io.flutter.embedded_views_preview as true in the Info.plist file. Check the docs for any update on this requirement.
See also
The Power of WebViews in Flutter
You can pass a data URI
Uri.dataFromString('<html><body>hello world</body></html>', mimeType: 'text/html').toString()
or you can launch a web server inside Flutter and pass an URL that points to the IP/port the server serves the file from.
See also the discussion in https://github.com/fluttercommunity/flutter_webview_plugin/issues/23
See https://flutter.io/docs/development/ui/assets-and-images#loading-text-assets about how to load a string from assets.
See https://flutter.io/docs/cookbook/persistence/reading-writing-files for how to read other files.
#Suragch, your code doesn't work as you posted it, it says localUrl was called on null.
_loadHtmlFromAssets needs to be called after assigning the controller :
onWebViewCreated: (WebViewController webViewController) {
_controller = webViewController;
_loadHtmlFromAssets();
}
Then it works fine :)
You may use Flutter InAppWebView Plugin. It will create a local server inside the app and it’ll run the HTML app there in the WebView. Start your server:
InAppLocalhostServer localhostServer = new InAppLocalhostServer();
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
await localhostServer.start();
runApp(new MyApp());
}
//... ...
class _MyHomePageState extends State < MyHomePage > {
//... ...
#override
void dispose() {
localhostServer.close();
super.dispose();
}
}
And then point your localhost html index file in the WebView.
InAppWebView(
initialUrlRequest: URLRequest(
url: Uri.parse('http://localhost:8080/assets/index.html')),
),
In many cases it doesn't work for many people because they forget to add all the folders as the assets in the pubspec.yaml file. For example, you need to specify all the folders and index file like below:
assets:
- assets/index.html
- assets/css/
- assets/images/
- assets/js/
- assets/others/
You can see this tutorial for further details.
I have the same problem; this is how I solved it.
Add webview_flutter to your project dependencies:
webview_flutter: 0.3.14+1
Create a WebViewController inside your screen/stateful widget
WebViewController _controller;
Implement the WebView and assign a value to the _controller using the onWebViewCreated property. Load the HTML file.
WebView(
initialUrl: '',
onWebViewCreated: (WebViewController webViewController) async {
_controller = webViewController;
await loadHtmlFromAssets('legal/privacy_policy.html', _controller);
},
)
Implement the function to load the file from the asset folder
Future<void> loadHtmlFromAssets(String filename, controller) async {
String fileText = await rootBundle.loadString(filename);
controller.loadUrl(Uri.dataFromString(fileText, mimeType: 'text/html', encoding: Encoding.getByName('utf-8')).toString());
}
You can use my plugin flutter_inappwebview, which has a lot of events, methods, and options compared to other plugins!
To load an html file from your assets folder, you need to declare it in the pubspec.yaml file before use it (see more here).
Example of a pubspec.yaml file:
...
# The following section is specific to Flutter.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
assets:
- assets/index.html
...
After that, you can simply use the initialFile parameter of the InAppWebView widget to load index.html into the WebView:
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
Future main() async {
runApp(new MyApp());
}
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
#override
void initState() {
super.initState();
}
#override
void dispose() {
super.dispose();
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: InAppWebViewPage()
);
}
}
class InAppWebViewPage extends StatefulWidget {
#override
_InAppWebViewPageState createState() => new _InAppWebViewPageState();
}
class _InAppWebViewPageState extends State<InAppWebViewPage> {
InAppWebViewController webView;
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("InAppWebView")
),
body: Container(
child: Column(children: <Widget>[
Expanded(
child: Container(
child: InAppWebView(
initialFile: "assets/index.html",
initialHeaders: {},
initialOptions: InAppWebViewWidgetOptions(
inAppWebViewOptions: InAppWebViewOptions(
debuggingEnabled: true,
),
),
onWebViewCreated: (InAppWebViewController controller) {
webView = controller;
},
onLoadStart: (InAppWebViewController controller, String url) {
},
onLoadStop: (InAppWebViewController controller, String url) {
},
),
),
),
]))
);
}
}
unzip the apk package,I found the reason: path is wrong;
For Android:
"assets/test.html" == "file:///android_asset/flutter_assets/assets/test.html"
so,just like this:
WebView(
initialUrl: "file:///android_asset/flutter_assets/assets/test.html",
javascriptMode: JavascriptMode.unrestricted,
)
you can load "assets/test.html".
The asset_webview plugin is specifically designed for this. Fewer features than other plugins, but simple to use.
Use flutter_widget_from_html_core---->
link -> https://pub.dev/packages/flutter_widget_from_html_core
dependencies:
flutter_widget_from_html_core: ^0.5.1+4
Code like this
HtmlWidget(
"""
<html lang="en">
<body>hello world</body>
</html>
""",
),
Finally found a proper way
String webview_content = '''
<!DOCTYPE html>
<html lang="en">
<head>
<title>Load file or HTML string example</title>
</head>
<body>
<h1>Local demo page</h1>
<p>
This is an example page used to demonstrate how to load a local file
or
HTML
string using the <a
href="https://pub.dev/packages/webview_flutter">Flutter
webview</a> plugin.
</p>
</body>
</html>
''';
final Completer<WebViewController> _controller =
Completer<WebViewController>();
Future<void> _loadHtmlString(
Completer<WebViewController> controller, BuildContext context) async {
WebViewController _controller = await controller.future;
await _controller.loadHtmlString(webview_content);
return WebView(
initialUrl: 'https://flutter.dev',
onWebViewCreated:
(WebViewController webViewController) async {
_controller.complete(webViewController);
_loadHtmlString(_controller, context);
},
),
I follow #Suragch answer and find that local image path in the html file cannot be loaded. So I tried a few ways and found that replacing the method loadUrl() with loadFlutterAsset() actually do the job (the code is also more simple).
class UserGuidePage extends StatefulWidget {
final UserGuideArguments arguments;
const UserGuidePage({required this.arguments, Key? key}) : super(key: key);
#override
State<UserGuidePage> createState() => _UserGuidePageState();
}
class _UserGuidePageState extends State<UserGuidePage> {
late WebViewController _controller;
#override
Widget build(BuildContext context) {
return WebView(
initialUrl: 'about:blank',
onWebViewCreated: (WebViewController webViewController) {
_controller = webViewController;
_loadHtmlFromAssets();
},
);
}
void _loadHtmlFromAssets() {
_controller.loadFlutterAsset('assets/index.html');
}
}
You can get the page html and use it to load the page with code below that is an example
import 'dart:convert';
import 'package:aws_bot/Utils/Const.dart';
import 'package:aws_bot/Utils/User.dart';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
